Some steroidal analogues embodying the hitherto unknown 13(148)-abeo skeleton have been synthesized by Fe(II)-induced rearrangement (tandem β-fission/reductive alkylation) of 14α-hydroperoxy-7-en-6-ones. The configurational assignment was made by t

The Wittig reaction of methoxymethyltriphenylphosphonium chloride (11) with 2,3,8,8a-tetrahydro-6-hydroxy-5-methoxy-1-methylcyclopent[ij]isoquinolin-7(1H)-one (4), obtained from 1,2,3,4-tetrahydro-6,7-dimethoxy-2-methylisoquinoline-1-acetic acid (6)

Urine of rabbits and rats treated with large doses of 3-methyl-4-phenyl-3-butenamide (I) was analyzed. Four metabolic products were isolated and identified: 2-hydroxy-3-methyl-4-phenyl-3-butenamide (II), 3-methyl-4-(4'-hydroxyphenyl)-3-butenamide (II

A new simplified technique is described for the isolation and separation of phytoecdysones from kaladana seeds. Using this method ecdysone, crustecdysone, muristerone A, kaladasterone, calonysterone and makisterone A were obtained. In addition methyl

Crustecdysone (I) is degraded by a lysed mycelium of the micro-organisms Rhizopus arrhizus, Rhizopus nigricans and Curvularia lunata to give poststerone (VI) which is then transformed into rubrosterone (VIII); makisterone A (II) behaves similarly, mu

1. Ring cleavage of 2,3-dihydroxybenzoate by cell-free extracts of Pseudomonas putida leads to 2-hydroxy-6-oxo-(2Z,4E)-hexa-2,4-dienoic acid and CO2. 2. The 1H n.m.r. spectrum of the ring-fission product obtained in a 2H2O solution suggests that the
